Not really. That’s a big problem, in my opinion – raising ticket prices doesn’t really discourage people from visiting, so it’s just as crowded, but paying more to visit raises expectations. When folks pay more and more to visit but have fewer opportunities to ride rides, it makes them resentful.
European and South American visitors get massive multi-week package discounts not available to Americans, so it’s quite inexpensive for them to go in large groups and stay for two weeks or so, often with free or heavily-discounted meal plans and hotel rooms. So it’s very common to see huge South American tour groups and sports teams there for various events. In my experience, that’s where much of the crowding is coming from.
